These natural processes reduce soil nutrient content and lifespan, result in reduced plant growth and yield, and ultimately translate to lower profits for tomato producers. As an alternative to unsustainable practices such as the use of synthetic fertilizers, producers are looking to environment-friendly soil ameliorants such as verimcompost leachate, an organic liquid produced from earthworm-digested material and casts that occur during the vermicomposting process.http://phys.org/news335786063.html

And although plants may appear static, even the tiniest seedlings are sophisticated organisms that sense and respond to their environment.

BiologyTue, 21 Oct 2014 10:53:43 EDTnews333107614LEDs shine in bedding plant production studyGrowers of annual bedding plant seedlings or plugs work to produce compact, fully rooted transplants with a large stem diameter and high root dry mass—qualities that make seedlings less susceptible to damage during shipping and transplant. To achieve these desirable qualities, greenhouse growers in northern latitudes must rely on supplemental lighting from high-pressure sodium lamps during winter months. A new study shows that light-emitting diodes (LEDs) can give greenhouse growers other lighting options that produce favorable results.http://phys.org/news325160239.html

But wild plants need to be more careful. In the wild, a plant whose seeds sprouted at the first warm spell or rainy day would risk disaster. More than just an insurance policy against late frosts or unexpected dry spells, it turns out that seed dormancy has long-term advantages too: Plants whose seeds put off sprouting until conditions are more certain give rise to more species, finds in a team of researchers working at the National Evolutionary Synthesis Center in North Carolina.http://phys.org/news317048758.html

Scientists explain mechanism behind phototropismPlants have developed a number of strategies to capture the maximum amount of sunlight through their leaves. As we know from looking at plants on a windowsill, they grow toward the sunlight to be able to generate energy by photosynthesis. Now an international team of scientists has provided definitive insights into the driving force behind this movement—the plant hormone auxin.http://phys.org/news288954299.html

The study, just published in the journal Tree Physiology, shows that common native red oak seedlings grow as much as eight times faster in New York's Central Park than in more rural, cooler settings in the Hudson Valley and Catskill Mountains. Red oaks and their close relatives dominate areas ranging from northern Virginia to southern New England, so the study may have implications for changing climate and forest composition over a wide region.http://phys.org/news254502854.html
